Gorzelanny, who did not pitch after Sept. 2, underwent what Ash described as a "cleanup" of the joint and is expected to be rehabbing until mid-March. Because he is ticketed for a bullpen role, the Brewers think Gorzelanny will have enough time to be ready by Opening Day.

"He wasn't really progressing from that shoulder issue he had toward the end of the year, so he asked for a second opinion with [Mets medical director Dr. Richard] Altchek," Ash said. "Dr. Altchek recommended what I would in layman's terms classify as a little cleanup of the acromion, which is a little bone in your shoulder."
